Top-of-mind questions for buyers
What does the free Product Access unit give me for stamps and philately auction data?
Product Access grants you a subscription to the stamps and philately auction sales data included with this listing. It draws on auction and private-sale transaction records. A single unit unlocks the data; there are no per-seat or per-record charges layered on top.
Does my cost change if I query more records or add more users?
No. This listing carries one free Product Access dimension with a flat structure. Cost does not scale with query volume, record count, or number of users. Nothing in the pricing triggers an added charge, since access is granted at no cost.
How is the auction sales data delivered and kept current after I subscribe?
